Which of the following is incorrect?

If something is moving at constant velocity, then there are no forces acting upon it.

Even at the top of its arc, a tennis ball always experiences constant acceleration when it is bounced.

When an object is in free-fall, it is weightless.

Newcastle united ARE the best football team!

Which of the following are incorrect when applied to Newton's third law?

Each force acts on the same object

Forces are opposite in direction

Each force has the same fundamental nature

Why is it inefficient to push a box along the ground rather than drag it along behind you?

Vertical component of force is directed towards the ground, increasing friction.

Pushing has less force than pulling

Horizontal component of the force is directed in the direction that the box is moving

More force is directed in the horizontal plane when pulling compared to pushing.

The compression of your finger when pressing the surface of your desk is direct evidence for:

The desk applying an equal and opposite force to your finger

The presence of a non-contact force

The fact that objects do not contain a force

Which of the following is correct?

Objects that have more inertia have more mass.

An object that is not moving does not have inertia

Two objects that are moving at the same speed have the same inertia

An object in notion has more inertia than an object at rest

With relation to forces, what is terminal velocity?

When density of the falling body equals the gravity imposed
